Browser-based image compressor
Compress images for websites, apps, emails, and content workflows without uploading files to a server. Choose image quality, set maximum dimensions, and convert the output to JPG, PNG, or WebP.
Images are processed locally in your browser. The selected file and compressed result are not uploaded to oddkit.
Common use cases
- Reduce website image weight before publishing
- Optimize screenshots and content images
- Create smaller assets for prototypes and documentation
Supported formats
JPG, PNG, and WebP input images are supported. Output can keep the original format or be converted to JPG, PNG, or WebP.
FAQ
Are my images uploaded to oddkit?
No. Compression runs locally in your browser using Canvas.
Which formats can I compress?
You can compress JPG, PNG, and WebP images, then download JPG, PNG, or WebP output.
Why can PNG output be larger than the original?
PNG is lossless, so reducing quality may not shrink it like JPG or WebP. Use WebP or JPG for stronger compression.
